This is really an English problem (I speak Spanish). Sorry for the way I write here. I had this device in the past but I can't find itin the Internet because I don't know the name in English. It will be hard to explain but I'll try. When you have a cordless drill with a bit socket, usually the screw is in front of you. But when the screw is in one of the sides you need something that let you use the drill in a 90 degree angle. I know there are some chucks that does this job, also some drills, but both are much bigger than the space I have. What I am looking for is a Philips screwdriver bit with a very little adapter (aprox. 1 1/2 width) that changes the direction of the rotation in 90 degrees. I hope I was enough clear. Thanks. Alex.
